The erythrocyte count increases after a while when an individual goes from a low to a high altitude because: the temperature is lower at higher altitudes. the basal metabolic rate is higher at high altitudes. the concentration of oxygen and/or total atmospheric pressure is higher at higher altitudes. the concentration of oxygen and/or total atmospheric pressure is lower at high altitudes.
